To aZZ'zI/'hom it may concern/:n l

Be it known that I, WILBERT W.l LAMB, a

" citizen of the United States, residingA at Chitation and Melting Snow and Ice, the following is a s ecification.

cago, in the county of Cook and State of Illino1s, haveinvented certain new. and useful Improvements in Devices for Burnin 'Vegebwhich My invention re ates to improvements: in devices for burning vegetationV and meltin snow and ice -on railways and highways; an the objects of my improvement are, first, to provide a generator of such-form and capacity as to supply hydrocarbon fuelin a gaseous state in a sufficient quantity to burn ve etation or melt snow andic'e, moving the vehicle more rapidly than has been possible heretofore.' y

With the'above and other'objects in view this invention consists of the novel forms and the combinations and arrangement'of arts hereinafter more specifically described,

like numerals of reference indicate correlspondinglparts throughout the several views, and in W c Figurel is a side elevation Aof the vehicle for surface Work. Fig. 2 is a side elevation of l the car for railroad-work. Fig. 3 is a bottom plan'view of the burner mechanism. Fig. 4

is a vertical section of a Bunsen burner, and Fig. 5 is a section on lin'e 5 5 of Fig. 3.

- Any suitable vehicle may be'used. I-

have shown an automobile of the ower-dray v air-pump and pressure-gage, as they are common means for such purposes in the automobile and railway arts.' y

Experience has shown that for practical railroad andsurfacework to be of economical Specification o'f Letters atent. rAppliii'eu filed December-15, 1905. Serial No. 291,942.

Patented prima 1907.1

andprofitable use the vehicle with theburnerdevices must be moved sufficiently rapid to .cover alarge area in agiven time, and this. 1

callsfor a large amount of fuel in the form of 6o gas.' It' is. desirable, as far as possible, t eliminate friction -or obstructions inthe passage of the fuel from the source of supply to the burners, and therefore I have provided generator and burner mechanism of large ca-4 65 paclty and composed oftwo sets of relatively large. generating-coils orI series of sl of plpe 7, horizontally disposed, each positioned at one side and at `right angle with the center line of vehicle travel, each coil terminating in 7o a straight portion 8,. positioned below and parallel with the coils. Thel straight lpor- -tions 8 extend'toand are connected with opries a multiplicity of Bunsen burners 11, ver- 7 5 I 'tically dis osed. The Bunsen'feeder carries numerous individual feed-pi es 10, extending to the rear and to the front t ereof, and at the f Aouter end of each individual pipe 10 is la -Bun-f sen burner 11, adapted to burn hydrocarbonl 8o fuel. VAt each end of the Bunsen-feeder 9 I provide a suitable quick-closing valve 12, operated by rodl 13 for the p ose of regulating the supply of fuel to thelllurners.

I prefer to use the form of Bunsen burner .8 5 shown in Fig. 4, in Which 14' represents the usual needle-valve and the inner end of rod 14. I show only tworows of Bunsen burners, one infront and the other at the rear of the Bunsen feeder. Itwill be apparent my 9o construction will ermit a number of'rows lof burners all to be ed from one.Bunsen feeder.

It will also be ap arent that by increasing the sizes and num er of parts reat capacity may be obtained. In Fig. 1 t e burner de- 95 vices are infront and in Fig. 2 they are vat the rear of the vehicle. The coils 7 and the straight pipe 8 constitute the generator proper, and when the generator is in full op- 4 eration there Will not be any liquid fuel in ico the Bunsen feeder 9. f v

The burner mechanism is supported upon an upright frame with parallel side standards 15 and a roller .16, over which the cable 17 runs. The inner end of the cable 18 is 1,05

adapted to be wound on a drum 19, the shaft ner.

cables 27 are fastened` to the standards 15 at 28 to prevent the burner mechanism dro -v 28 e-.

ping onto the round accidentally. notes a bracear to stay the side standards 15.

The tank 29 is for liquid fuel and is conncted with supply-pipes 6. Near the tank there is a valve 30 in each pipe to shut olf the fuel from the tankwhen des1red.

Su ply-pipes 6 are piotally joined at 3.1 to al ow vertical adjustment of the burner means. 20 is a hood just above" and extending the entire length of the Bunsen feeder for the urpose of deflecting the heat downward. The ood is suitably fastened to and sup orted by the frame 20 near either end be ind the inner roW of Bunsen burners.

Before beginning to operate the burner it is desirable to rotate the needle-valve 14, rod

414', one full turn from closed osition. The4 bunsens are lighted in the we l-known man- When the bunsens are burning the proper mixture of gas and air, the flame may e controlled 'at will by means of the quickaction valve 112.

` Having thus fully described my invention, whatI claim a's new, and desire to secure by Letters Patent, is-

1. In a vegetation-burner, a Bunsen feeder i Witnesses:

' carr I g a multi licityof Bunsen burners, in-

com inationwit generatingdevicescompris-v ing coiled portions of pipeV and straight portions positloned below and parallel with the coils and connected with o posite ends of the Bunsen feeder, and a fue -regulating Valve` 1 the coiledM valve between the generator and the unsen l feeder.. A

3. In a vegetation-burner, a plurality-.of

horizontally-disposed coils'of pi e each coil having a straight extension t e'reof positioned below and parallel with the coils and constituting a generator, and-means for regulating the flow of fuel from the' generator, in

combination with 'a Bunsenfeeder carryingv a multiplicit of Bunsen burners,` and means for distributlng liquid fuel to the generator.

In testimony whereof I affix my signaturel in presence of two witnesses.
